Quick and easy Spaghetti with Sausage is ready in just 45 minutes, all in one pot!
Add pork sausage, ground beef, onion, garlic, salt, and pepper to a large pot over medium-high heat on the stove. Cook 15 minutes until the meat crumbles and cooks through.
Pour in chicken stock and spaghetti sauce, then add spaghetti noodles and red pepper flakes to the pot. Raise the heat and bring to a boil, stirring so the spaghetti does not stick together or to the bottom of the pot.
Once boiling, lower the heat to medium and simmer for 15-20 minutes, stirring occasionally to keep the noodles from sticking to the pot.
Remove from heat. Top with parmesan and parsley, serve, and enjoy!
